Firefox beta update supports HTML 5

Mozilla released an update for the ongoing Firefox beta, bringing the current version to 3.1b3. This will be the last beta before the version number changes to 3.5, according to the organisation.

Among the changes to Firefox 3.1b3 is support for some elements of HTML 5, including the video and audio tags. The update also adds support for the W3C Geolocation API, JavaScript query selectors, CSS 2.1 and 3 properties, SVG transforms and offline applications.

The private browsing mode in Firefox has been improved and the JavaScript engine was updated to improve performance and stability. The Gecko layout engine has been improved as well, allowing for faster content rendering.

The update to Firefox brings its feature set more inline with the most recent public beta of Safari 4, which also added support for the latest Web technologies.
